I am replacing my entire exhaust and have the following question about my 1989 coupe I am planning not to put back on the main cat. and am confused about what to do with the air tube fitting that connects to the cat. Can I just cap the end some how. I don't want to do anything permanent incase I ever need to put back on the cat.
thanks in advance
Mike
